ADJUSTING DEVICE FOR- THE- CUTTING ETIPJEES OF FOOD CHOPEEES.

Applieation fi'led June 11,

To aZZ whom it may concern g Be it known that I, ARTHUR Tiiinniv, a citizen of the United States of America, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Adjusting Devices for the Cutting Plates of Food Choppers, of which the following is a specification.

This invention relates to an improvement in adjusting devices to be used in connection with the cutting edge plates of grinding or cutting machines such as food choppers, and has for its primary object the purpose of providing a removable packing element which is made co-operable with a worn cutting edge plate for compensating of the wear of said plate.

Another object of the invention is in providing a packing ring to be used between the cutting edge plate and the holding nut of a food chopper.

A further object of the invention is in; providing a packing ring which is made reversible.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying, drawings, exemplifying the invention and in which Figure 1 is an end elevation of the discharge end of a food chopper showing this improved packing element used in connection therewith.

Figure 2 is a fragmentary longitudinal. vertical section taken approximately on the line II-II of Fig. 1.

Figure 3 is a side elevation of the packing element or ring.

Figure 4-. is an end elevation of Fig. 3.

With reference to the accompanying drawings, 1 designates the cylinder of a food ch0pper having the spiral feed 2 turnably located therein, and mounted on the squared portion 3 of said spiral feed is a cutter 4, said squared portion. being formed on the end shaft 5 of the spiral feed 2.

An annular seat 6 is formed in the discharge end 7 of the cylinder 1, and mounted within said seat and adapted to bear against the annular shoulder 8 is a cutting edge plate 9 bearing a plurality of apertures 10, said plate being provided with a centrally arranged hub 11 in which is formed a hori: zontal bearing 12, said bearing being for the support of the end shaft 5.

The cutting edge plate 9 is provided with 1923. Serial No. 644,630.

notch 13 on itsperiphery, said notch bein i 1 73 f or thereception of a pro ection 1 1 which is extended within the seat- 6, said projection being adapted to prevent the plate 9 from being revolved.

Vt ithin the annular seat 6 is a packing ring 15 which is trans-split at 16, said ring being provided with a pair of oppositely disposed outwardly projecting portions 17, and a radially projecting portion 18. The projecting portion 18 of the ring 15 is adapted to engage the annular seat 6 whereas one of the projecting portions 1'? will bear against the outer face of the cutting edge plate 9.

The, discharge end 7 of the cylinder 1 is threaded interiorly as designated at 19, said threads being for the reception of the holding nut20, which when drawn on the threads 19 will have the inwardly extending lip 21 thereof bear against one of the side faces of the radially projecting portion 18 of the ring 15 as shown in Fig. 2. i

The disclosure of the drawings shows this improved adjusting device in use after the cutting edgefplate 9 has become worn by the operating of, the cutter 4c thereagainst and by the regrinding of the worn side of said cutting edge plate, this improved manner of adjusting only being used when the cut ting edge plate has been worn to such an extent whereby the inwardly extending lip or flange 21 of the holding nut 20 can. not provide a take-up thereto.

In mounting the packing ring 1.5 in place, the holding nut 20 is removed from the threaded end of the discharge end 7 of the cylinder 1 and the packing ring'15 is mounted in place in which one of the outwardly projecting portions of the ring will bear against the outer face of the cutting edge plate 9 surroundingly of the apertures 10 thereof and in which the adjacent annular recess 22 of the ring 15 will provide for the reception of the projection 14 so that clearance will be given to said projection to prevent the ring from engaging thereagainst when the holding nut 20 is remounted on the threads 19 of theicylinder 1.

The holding nut 20 is then drawn on the threads 19 and the extending lip 21 will bear against one side of the projecting portion 18 of the ring thereby forcing the abutting projection 17 of said ring into clamping relation with the cutting edge plate 9.

On account ofthe radially projecting portion 18 of the packing ring 15 being arranged centrally oi' the outwardly projecting portion 17 of said ring, said ring is made reversible so that the operator when placing the ring in adjusting position can abut either of the projecting portions 17 against the cutting edge plate 9.

From the disclosure of this invention, it is obvious that after a cutting edge plate becomes worn, the application of an improved adjusting means of this character will permit further use of the worn cutting edge plate.

What I claim is I 1. In a food chopper, the combination of a cuttingelement, a cutting edge plate c0 operable with said element, extending means for preventing said plate from turning, a removable packing element adapted to bear against said plate having means formed thereon for providing clearance to said we tending means, and a holding member for said packing element.

2. In a food chopper, the combination of a cutting element, a cutting edge plate 00- operable with said element having a notch formed in its periphery, a projection for cooperation with the notch of said plate for pre venti u cutting element, an apertured cutting edge plate co-operalole with said element, a packring having an outwardly extending intermediately arranged annular projecting portion adapted to bear against said plate and surround the apertures thereof, and a holding element for said ring.

In a food chopper, a cylinder therefor, a cutting element located in said cylinder, a seat formed at one end of said cylinder, a cutting edge plate located in said seat having a notch formed in its periphery, a projecting portion located in said seat for cooperation with the notch or said plate, a reversible packing ring located in said seat ada )ted to bear a ainst said late and having means provided on each side for co-operation with said projecting portion, and'a holding member adapted to bear against said ring.
